And G: Something similar seems to have existed at an early development stage as there is a leadership progression table in the data section, but it would be too complicated to reimplement.
Hmmm, how about this then?
Leadership = gives the entire stack +1Attk, +1Def, +1Res, +4Mov....and we can just adjust the cost of the ability to match it's value afterwards (maybe 30-40 skill points).
Even if you can't do the +4 movement, just the +1Attk, +1Def, +1Res would still make Leadership an more lore immersive skill.
This way, there is no need to implement a fragmented concept that was never finalized.....while we can now save skill points to try to turn our leaders into...well, leaders!
As for IniochReborn's suggestion of all of us playing online, that would be epic! I'm down for it!
